The total percentage they travelled when Jai fell asleep is 35%.
In mathematics, a percentage is a ratio or value that is expressed as a fraction of 100. The Latin term "per centum," which means "by a hundred," is the source of the English word "percent." The sign "%" stands for percentage. We apply the percentage method to determine the portion of a whole expressed in terms of 100. Use the percentage formula to convert a number to a fraction of 100.
The total length of trip was 740 miles.
Jai travelled before they fell asleep = 259 miles
Therefore the percentage of total trip travelled before Jai fell asleep =
= [tex]\frac{259}{740}\times100[/tex]
= 35 %
So by 35% of the total trip, they travelled when Jai fell asleep.

5 is the correct scale factor
This is because there are 5 little segments that go from C to the larger point in the top right corner. We need 5 pieces of segment CB to get segment CB' where B' is that top right corner point.
Put another way: If the distance from C to B is 1 unit, then the distance from C to B' is 5 units. This shows the distance has multiplied by 5, and that's the scale factor.

The hobbits Frodo, Sam, Pippin and Merry have breakfast at different times. Each one takes a quarter of the porridge in the pan, thinking that the other three have not yet eaten. What fraction of the porridge is left after all four hobbits had their breakfast?
Step-by-step explanation:
Let us start with Frodo's breakfast. He starts eating a quarter of the porridge. Let us say the porridge is 100 spoons, to make dividing easier. After Frodo we have [tex]\frac{3}{4}[/tex] left of the original bowl; we are left with 75 spoons.
100 - [tex]\frac{1}{4}[/tex] = 100 - 25 = 75
Next, comes Sam's breakfast. He eats 75 - [tex]\frac{1}{4}[/tex] = 75 - 18.75 = 56.25 spoons left.
Next, we have Pippin's breakfast. He eats 56.25 - [tex]\frac{1}{4}[/tex] = 42.1875 spoons.
Lastly, we have Merry's breakfast. He eats 42.1875 - [tex]\frac{1}{4}[/tex] = 31.640625 spoons.
Now, we know we have 31.640625 spoons left. However, we need to know what fraction this is out of the original porridge bowl. So, we do:
31.640625 * 100 = 3164.0625 * 1 = 3164.0625
3164.0625% of the bowl remaining!
What a yummy breakfast!

A coin is tossed and a die is rolled. What is the probability that the coin lands heads up and the number rolled is a 6 ?
The probability that the coin lands heads up and the number rolled is a 6 is 1/12.
Given that a die is rolled and a coin is tossed.
We have to find the probability that the coin lands heads up and the number rolled is a 6.
Probability of getting heads in tossing a coin = 1/2
Probability of getting 6 in rolling a die = 1/6
The event of tossing a coin and rolling die are independent.
Hence,
Probability that the coin lands heads up and the number rolled is a 6 =
Probability of getting heads in tossing a coin * Probability of getting 6 in rolling a die = (1/2)*(1/6) = 1/12.

Abdoulaye is driving on a long road trip. He currently has 11 gallons of gas in his car. Each hour that he drives, his car uses up 1 gallon of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after tt hours?
The amount of gas he would have in the tank after 3 hours is 8 gallons.
The gas left after tt hours is 11 - tt.
How much gas would be left in the tank?In order to determine the amount of gas that would be left in the tank, the amount of gas used would have to be subtracted from the initial amount of gas in the car.
Subtraction is the mathematical operation that is used to determine the difference between two or more numbers. The sign that is used to represent subtraction is -.
Amount of gas left = initial amount of gas - (gas used per hour x number of hours travelled)

Points A and B have coordinates A(-4,2) and B(3,-6). Find the coordinates of point P, the weighted average of points A and B, in which point A has a weight of 4 and point B has a weight of 3.
A (-7/2, -5)
B (-1,-10/7)
C (-1/2, -2)
D (0,-20/7
The coordinates of the point P is P(x, y) = (- 1, - 10 / 7). (Correct choice: B)
How to determine the coordinates of a resulting point by weighted averages approach
In this problem we find the coordinates of two points on Cartesian plane, of which we must determine the location of a third point by using a formula based on a weight average-like formula:
P(x, y) = (4 / 7) · A(x, y) + (3 / 7) · B(x, y)
P(x, y) = (4 / 7) · (- 4, 2) + (3 / 7) · (3, - 6)
P(x, y) = (- 16 / 7, 8 / 7) + (9 / 7, - 18 / 7)
P(x, y) = (- 7 / 7, - 10 / 7)
P(x, y) = (- 1, - 10 / 7)
The coordinates of the point P is P(x, y) = (- 1, - 10 / 7).

Write an equation in slope-intercept form for the line described.
passes through (-12,3), perpendicular to y=-2/3x-11
The equation in slope-intercept form for the line that passes through (-12,3), perpendicular to y = -(2/3)x-11 is y = (3/2)x + 21.
The slope intercept form of a line is:-
y = mx + b
Where:-
m represents the slope of a line
b represents the y-intercept of a line
x and y represent the ordered pairs (x,y) throughout a line
We are given the line y = - (2/3)x-11 is perpendicular to the line whose equation we have to find.
Hence,
slope of the line*(-2/3) = -1
slope of the line, m = 3/2
Also, (-12,3) passes through the line,
Hence,
3 = (3/2)*(-12) + b
3 = -18 + b
b = 21
Hence, the equation of the line in slope intercept form is y = (3/2)x + 21.

Step-by-step explanation:
You want the height drawn on each triangle corresponding to the base shown.
HeightThe height of a triangle is the perpendicular distance from the base to the opposite vertex. The point at which the height segment meets the base may or may not lie on the triangle.
The height segments for the two given triangles are shown in the attachment.
__
Additional comment
As this problem suggests, any side of a triangle may be designated the "base."
The height segment is also called an altitude. When all three altitudes are extended until they coincide, the point at which they meet is called the "orthocenter" of the triangle.
The orthocenter of an acute triangle lies inside the triangle. For a right triangle, it lies at the right-angle vertex. For an obtuse triangle, the orthocenter is outside the triangle.

Find the sum of each series. Σ⁵ n=1 (3 n+1)
The sum of the given series is 50
The summation notation or sigma notation is used to simplify the writing of long summation into a single formula.
The given series in sum notation is:
[tex]\sum\limits^5_{n=1} {(3n+1)}[/tex]
Substitute n = 1 ...5 into the nth term formula inside the sum notation:
a(1) = 3 . (1) + 1 = 4
a(2) = 3. (2) +1 = 7
a(3) = 3. (3) +1 = 10
a(4) = 3. (4) +1 = 13
a(5) = 3. (5) +1 = 16
Hence, the series:
4 + 7 + 10 + 13 + 16
We can evaluate the sum directly by adding all the terms:
S(5) = 4 + 7 + 10 + 13 + 16 = 50
Or we can also use the sum formula of an arithmetic series:
S(n) = n/2 [a(1) + a(n)]
For n = 5
S(5) = 5/2 (4 + 16)
S(5) = 5/2 . 20 = 50

The lengths 12, 16, 10, 5, and 2 of the sides, AP, DQ, CS, PQ, and QR respectively, using the triangle proportionality theorem, gives the area of trapezoid BRSC as 40 square units.
What is the triangle proportionality theorem?The triangle proportionality theorem states that a line parallel to a side of a triangle and also intersects the other two sides, it divides the two sides proportionally.
Based on the theorem, where the other two sides are perpendicular, the parallel side divides the two sides equally.
The given parameters are;
The figure represented by ABCD = A parallelogram
The lengths of the sides of the figure are;
AP = 12
DQ = 16
CS = 10
PQ = 5
QR = 2
Required: The area of figure BRSC
Solution;
Given that ABCD is a parallelogram, we have;
AD = BC (definition of a parallelogram)
Using the triangle proportionality theorem, we have;
PQ = RS = 5 (segments bounded by equidistant parallel lines)
DQ - CS = AP - BR = 16 - 10 = 6 (Parallel vertical lines intersected by parallel lines at different heights)
AP - BR = 6
BR = 12 - 6 = 6
The area, A, of trapezoid BRSC is therefore;
A = RS × (BR + CS)/2
Which gives;
A = 5 × (6 + 10)/2 = 40

Given,
Here we need to find the value of x² values that separate the middle 80 % from the rest of the distribution for 20 degrees of freedom.
Based on the given details,
Degrees of freedom = 20
Middle separate value = 80%
Which is equal to 0.8 in decimal point.
The significance level
=> ∝ = 1 - 0.8
=> ∝ = 0.2
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing
=> 0.2/2= 0.1
So we will have two values for chi square
One with
